AI Summary & Key Takeaways
AI InsightThe hemodynamic changes and postoperative minor complications were also recorded.Results: Body mass index, neck circumference, Mallampati scores, and ASA physical status were statistically higher in the morbidly obese group (P 35) patients with the aid of some key maneuvers and with a statistically significant but clinically negligible prolongation of the intubation time.

Abstract
Background/aim: Increased body mass index (BMI) and neck circumference are the two independent predictors of difficult intubation. McGrath MAC X-Blade is a videolaryngoscope specifically designed for difficult intubations. Materials and methods: Eighty patients with the American Society of Anesthesiologists (ASA) physical status I?III undergoing elective surgery requiring endotracheal intubation were enrolled in the study. Patients were divided into two groups, nonobese (BMI 35). All patients were intubated with the McGrath MAC X-Blade in both groups. View optimization and tube insertion maneuvers such as reinsertion of the device, slight removal of the device, cricoid pressure, handling force, 90° anticlockwise rotation of the tube, use of stylet, and head flexion maneuvers were recorded. Cormack?Lehane grades, insertion times, intubation, and total intubation times were recorded. The hemodynamic changes and postoperative minor complications were also recorded.Results: Body mass index, neck circumference, Mallampati scores, and ASA physical status were statistically higher in the morbidly obese group (P 35) patients with the aid of some key maneuvers and with a statistically significant but clinically negligible prolongation of the intubation time.
